As I noted earlier, Kyanted has special ordered a number of chemicals for me, as has the Formulary. You just need to ask. Kyantec does not list Erythrosine, but I buy it there. They special order it for me.

Hi PE,

I spoke with a representative Kyantec earlier on today and they're looking into finding this chemical for me. BTW, do you know of any good texts on the above synthesis? I've had no luck on the internet. Thanks again for your help.
